Description

Carrier unit for an electronic media device

The invention relates to a carrier unit suitable for an electronic media device and to an electronic media device according to the preambles of claim 1 and claim 9 respectively. The following devices are considered an electronic media device, such as mobile phones, small devices such as so-called "handheld computers" and palmtop computers, but also include plug-ins for mobile phones, etc.

As for the plug-in of the mobile phone, it is known that not only the electronic components but also the necessary electrical structural components are to be plugged into the circuit board. This is achieved through technologies such as SMD, but this situation leads to many problems. One of the problems, for example, is that only those materials that can withstand the SMD soldering process can be used to manufacture electrical structural components. A further disadvantage is that these electrical components are in some cases of relatively large size and occupy a considerable amount of space on the circuit board, which is more suitable for electronic components. In addition, this technology is in the process of further miniaturization, especially circuit boards.

It is an object of the present invention to provide a carrier unit for an electronic media device, or to provide an electronic media device of the initially mentioned type, in which the layout and fixing of the electrical structural components enable the shaping of the device from a manufacturing technology point of view. quite small.

To achieve this object, a carrier unit of an electronic media device, or an electronic media device of the initially mentioned type, has the features indicated in claim 1 or claim 9, respectively.

As a result of the measures according to the invention, the electrical structural part takes up less space on the circuit board because of the use of elastic contacts, so that the above-mentioned circuit board can be equipped with more electronic components or have a smaller structure. Furthermore, the structural design of electrical structural components can also be independent of the needs of circuit board soldering operations from a material quality point of view; if exploited, this fact can allow one to produce electrical structural components in a more profitable manner. Furthermore, the aforementioned electrical structural components can be fixed mechanically in the carrier unit in a somewhat simpler manner. Finally, only the above-mentioned circuit board and the carrier unit need to be installed together to complete the assembly of the electrical structural components and the circuit board and their electrical contact, so the method is simpler.

The fixing of the electrical component on the carrier unit can be influenced in various ways. There are therefore various embodiments according to the features of claims 2 , 3 and/or 4 which serve this purpose.

According to the features described in claim 5, the carrier unit can be directly used to insert a SIM card, even an MMC card or a CCM inserting card in a desired manner. In this case, the features of claim 6 may be taken as prerequisites.

In order to realize the inner shielding, that is to say the shielding of the electronic components on the printed circuit board, the features of claim 7 should perhaps be provided in a certain advantageous manner. This is an easy to manufacture, effective shielding system.

The effect achieved by means of the features of claim 8 is that a considerable amount of space between the electrical structural parts is available for electronic structural elements on the circuit board, depending on the type of construction of the carrier unit.

When one or more circuit boards are used, according to one or more of the features of claims 10 to 12, a helpful solution to the problem arises with one or more carrier units.

By means of the features of claim 13 , the production and assembly of a media device with corresponding carrier units can be further simplified.

Further details of the invention can be seen from the following description, in which the invention is explained and described in great detail by means of exemplary embodiments shown in the drawings. In the attached picture:

Figure 5 shows, in exploded form and in the form of a mobile phone, a media device with a carrier unit made of insulating material, another form of embodiment of the invention;

Fig. 6 corresponds to Fig. 5 and shows a media device in the form of a mobile phone with an integrated carrier unit made of insulating material, which is a further exemplary embodiment of the present invention.

In FIGS. 1 to 4, an electronic media device in the form of a small, so-called "handheld device" includes a housing, at least one circuit board on which electronic components are mounted, and various electrical structural components. Shown in the figure is a planar carrier unit 11 of the present invention made of insulating material, which is installed or will be used to install many electrical structural parts, such as a switch 12, an audio connection part 13, a Antenna connection part 14, a plug socket 15, a group of finger contact strips 16 for plug-in 19 (for example, can be SIM card), one has for plug-in 20 (for example, can be MMC card) ) used with a pin header 17 with a set of spring contacts 18 on it. In this connection, "electrical structural parts" are understood not only as so-called "complete parts", but also those parts that are only partially prefabricated, such as sets of contacts, which are directly fixed by the carrier unit, while the above-mentioned The mechanical functions of the electrical components, such as guidance, are integrated into the carrier unit.

The following device is considered to be an electronic media device having a carrier unit of this type, equipped with one or more electrical structural components 12 to 18: such as a hand-held computer, resource organizer, palmtop computer, mobile phone (Figure 5 and A small electronic device in the form of Fig. 6) etc., even a small electronic device in the form of a card plug-in device used in mobile phones and the like. In this regard, the carrier unit made of insulating material may not only be a flat structure, but also a skeleton structure (outer frame) with connecting ribs (or grid shape), or even the simplest frame structure .

As shown in FIGS. 1 to 4 , the flat carrier unit 11 made of insulating material has a plurality of recesses and openings, which allow electrical components 12 to 18 and inserts 19 and 20 to be inserted. The carrier unit is made of blowable plastic. Surface areas of the carrier unit 11 can be metallized so that these areas can act as electrical shielding for electrical components on the printed circuit board, but this is not shown in the figures.

The switch 12 is mounted in a recess 22 adjacent to the area where the antenna connection part 14 is attached. There is also a U-shaped groove 23 to accommodate the audio connection part 13 which, like the switch 12, is operable from the outside of the carrier unit 11 made of insulating material and from the outside of the housing of the electronic media device. The plug socket 15, which is also operable from outside the housing of the electronic media device, is mounted in another U-shaped groove 25, which is located at the end face of the carrier unit 11 made of insulating material, on both sides. Between the two grooves 22 and 23. The switch 12 , the audio connection part 13 and the plug socket 15 are mechanically secured in their respective openings 22 , 23 and 25 in a form-locking manner. The plug socket 15 has spring contact pieces which are directed towards the circuit board and held elastically in the assembled form in corresponding conductor tracks of the circuit board for electrical contact. The same is true for the audio connection part 13 and the switch 12, but not shown in this way. The finger contact sheet group 16 is made up of two rows of finger contact sheets 16' and 16", one behind the other, is arranged and fixed in the ribs 31 and 32 between the openings 26, 26' and 27 for injection molding The way is surrounded by the plastic of the carrier unit 11. The contact rows 16' and 16" of the finger contact piece group 16 have spring contact piece ends 37 facing the circuit board on one side, and also have spring contact pieces pointing to the plug-in 19 that needs to be used 37.

On the opposite end of the carrier unit 11 made of insulating plastic to the groove 25 where the plug socket 15 is located, there are also two openings 28 and 29 adjacent to each other, which accommodate the pin row contacts 17 and the spring contact piece set 18. One side of the spring contact piece group has a spring contact piece 38 pointing to the circuit board, and the other side has a spring contact piece 39 facing the MMC plug-in 20. The above-mentioned MMC insert can be inserted into a wide slot-shaped opening 30, one end of which is located at the narrow end face 40 of the carrier unit 11 made of insulating plastic, and the other end is connected to the opening 29; An ejector (not shown) installed in the narrow slot 33 removes the card.

The carrier unit 11 made of insulating plastic, which mechanically securely connects the electrical components 12 to 18 , is kept at a distance from the associated printed circuit board on which the electronic components are plugged in a suitable manner. This can be accomplished with two cover parts of the electronic media device, or with a separate frame part.

FIG. 5 shows a mobile phone 50 as the media device mounted in a carrier unit 11' made of insulating material substantially equivalent to the carrier made of insulating material in FIGS. 1 to 4 unit 11, therefore, it is not necessary to describe it in more detail even if it is intended to make one or another change to the provided electrical structural components. In this exemplary embodiment, the carrier unit 11' is arranged between two circuit boards 51 and 52, shown in the figure, which are plugged with corresponding electronic components, but not shown. Inserted components. Furthermore, the mobile phone 50 has an upper cover 53, on which, for example, a keyboard 54 and a display 55 are mounted; and a lower cover 56, also shown only diagrammatically. The profile 57 of the carrier unit 11' is configured such that the mobile phone is completely or partly sealed by the covers 53 and 56 in the assembled state. In other words, the outer shell 57 of the carrier unit 11 ′ also at least partially forms the outer shell of the mobile telephone 50 .

Fig. 6 represents a mobile phone 60 as this electronic media device, and it has a circuit board 61, also has an upper machine cover 63 and a lower machine cover 66, among the figure, only schematically shows circuit board 61, but Any electronic structural elements on the circuit board 61 are not shown. As can be seen from the figure, the upper cover 63 has a keyboard 64 and a display 65 . In this exemplary embodiment, there is also a similar carrier unit 11 ″ made of insulating material, which is similar in structure to the carrier unit 11 or 11 ′, but differs from them in that the carrier unit 11 ″ is integrated into the In the machine cover 63 , or it constitutes the upper machine cover 63 . In this exemplary embodiment, as an example, the keyboard 64 is inserted into the carrier unit 11" from below (as shown in Figure 6). Obviously, the carrier unit 11" can also be placed on the other side of the circuit board 61, It is structured to constitute the lower cover 66 .

Obviously, where more than two circuit boards are used and are stacked one on top of the other, these also have carrier units, but in each case in a different form of multilayer construction. In contrast to the various exemplary embodiments described, the carrier unit made of insulating material can accommodate further, all or only partially provided electrical structural components, or also only some of the illustrated electrical structural components part. As mentioned earlier, the carrier unit can also not be in the shape of a flat plate with grooves, but can be simplified into a so-called "carrier skeleton", which includes an outer frame and several corresponding inner parts required for fixing electrical structural components. longitudinal and/or transverse connecting ribs. Frame shapes are also possible in the simplest cases. In this way, the space between the electrical structural parts can be used for electronic structural components mounted on the circuit board.
